JAVA_OPTS Variable Details

Memory Available to the Java JVM Increasing the memory available to the Java JVM JAVA_OPTS="-Xmx1024m -Xms256m" export JAVA_OPT Options description: -Xmx sets the maximum amount of memory that can be allocated to the JVM heap; here it is being set to 1024 megabytes. -Xms sets the initial amount of memory allocated to the JVM heap; here it is being set to 256 megabytes.

The source bean is not serialized and a final class. The source system does not allow doing it because of security breach. The source bean is very heavy and contains lot of nested beans. The source bean has fields of different types which may not be required for other system. The source bean has lot of fields; some of them are not required. Scenario to use Dozer Suppose You want to make a REST call or web service call to get the minimal account details of a person. But the source system has a bean called “Acc0untBean” which contains many sensitive information like person’s internet banking passw0rd, PAN no or social securit

It is a service which exposes an API over HTTP. Web Services allow applications developed in different technologies to communicate with each other through a common format like XML, Jason, etc.  Web services are not tied to any one operating system or programming language. For example, an application developed in Java can be used in C#, Android, Php etc., and vice versa.  Web Service is a connection technology, a way to connect services together into a S
